Islam this unknown religion: arabic version - This application consists in i-ebook which means interactive book. This is a new concept aiming "to give it life" by the incorporation, into each page, a button "Ask Author". The reader may use this button to ask the questions that he wants, directly to the author, on all aspects approached in the book or on related aspects. This book demonstrates the distortion of the main features of Islam which had continued for centuries; each generation contributed to such acts so that the original Islam, the one revealed to Muhammad (Mahomet), has become strange and unknown and all that has been retained is its name. The treated topics are designed to make a clear distinction between what is historical or political or what is purely secular thought and what is true Islam.
